FNB refusing to downgrade my accounts to gold!

I requested for my account to be downgraded from Premier to gold. More than a month later and escalating the matter multiple times through the secure chat function the account is still not downgraded. All they did is add an additional gold credit card account to my profile but I still have a premier cheque and credit account. How pathetic. The only thing their bankers do is tell me they have escalated to their managers and the issues will be resolved within 24hrs. Its been a month now and absolutely nothing has been done. What a bunch of ***********s!
